I have to agree. Sometimes I think I'm not disciplined enough. But every now and then I start a book which is so interesting and vital that I'm compelled to go all the way through at top speed, with later re-reads. I'm thrilled and altered as a result. That's what reading is like for me now. Unfinished books no less than unordered books are part of the search and nothing to be ashamed of.
